It doesn't make you bi, gay, straight, whatever you like to call it.
I agree with Alfred Kinsey that we're all a little bit gay, and that's why so many people can have gay experiences and still be "straight".
I'm bi, but I still think that all those labels (yes including "bi", I'm not a hypocrite) are all just arbitrary when it comes down to it.
I don't label myself either - and according to Kinsey there are 7 levels anyway - but I just find it funny to read so many posts here where a guy describes a long situation where he wanked off with someone or sucked their cock or even fucked them, and then they say "oh, but I'm not gay" It's like eating meat and then claiming to be vegan.
